flow-nexus-neural

flow-nexus-neural is a skill for Claude Code from ruvnet/ruflo. It costs 21 tokens per session (4,687 once invoked), scanned A, original, MIT.

A service for training and deploying neural networks in separate cloud workspaces. Neural networks are programs that learn patterns from data, and the supported types include feedforward, LSTM, GAN, autoencoder, and transformer models.

In plain words
What is it for?
Use it to train custom neural networks, choose a model architecture and resource tier, and deploy models through Flow Nexus.
Why use it?
It provides a managed place to run model training and deployment without keeping all training work on one machine.

About the project

Ruflo is an execution and coordination layer for Claude Code and Codex that equips AI coding agents with tools, memory, control loops, sandboxes, and collaboration mechanisms. Developers use it to organize specialized agents into swarms, coordinate workflows, retain knowledge across sessions, and communicate across machines. The catalogue entries are Ruflo’s skills, commands, agents, hooks, and plugin components.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

flow-nexus-neural scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Core Capabilities

1. Single-Node Neural Training

Train neural networks with custom architectures and configurations.

Available Architectures:

  • feedforward - Standard fully-connected networks
  • lstm - Long Short-Term Memory for sequences
  • gan - Generative Adversarial Networks
  • autoencoder - Dimensionality reduction
  • transformer - Attention-based models

Training Tiers:

  • nano - Minimal resources (fast, limited)
  • mini - Small models
  • small - Standard models
  • medium - Complex models

        { type: "dropout", rate: 0.3 },
        { type: "dense", units: 128, activation: "relu" },
        { type: "dropout", rate: 0.2 },
        { type: "dense", units: 64, activation: "relu" },
        { type: "dense", units: 10, activation: "softmax" }
      ]
    },
    training: {
      epochs: 100,
      batch_size: 32,
      learning_rate: 0.001,
      optimizer: "adam"
    },
    divergent: {
      enabled: true,
      pattern: "lateral", // quantum, chaotic, associative, evolutionary
      factor: 0.5
    }
  },

  user_id: "your_user_id"
})
Example: LSTM for Time Series
mcp__flow-nexus__neural_train({
  config: {
    architecture: {
      type: "lstm",
      layers: [
        { type: "lstm", units: 128, return_sequences: true },
        { type: "dropout", rate: 0.2 },
        { type: "lstm", units: 64 },
        { type: "dense", units: 1, activation: "linear" }
      ]

      epochs: 150,
      batch_size: 64,

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

flow-nexus-neural is a skill published in the GitHub repository ruvnet/ruflo (71,489 stars, last pushed yesterday), licensed MIT. It adds 21 tokens to every session and 4,687 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
